Short term and long term planning for the disposal of dredged material can be significantly enhanced using state-of-the-art computer modeling. Computerized mathematical models can be constructed to perform expedient and consistent evaluations of alternative disposal site selection and management options. Spatial data analysis technology is used to construct a grid cell data bank of pertinent physiographic characteristics, which can then be accessed and manipulated by computer programs to assist in site selection. The output is a computer-generated map which identifies a portfolio of candidate disposal sites in rank order according to a user-specified hierarchy of selection criteria. A second computer model is used to evaluate various management options and refine the selection and use of sites under consideration. 8 refs.
